    摘要: The invention relates to a method for detecting the position of an object within the interior or a vehicle equipped with a door (4). The inventive method is characterized by recording a sequence of images by means of a camera (2) and calculating the actual position of the object by electronically evaluating the images of the sequence of images, and generating a differential image by comparing an actual recorded image with a previously stored image. The position of the object is calculated on the basis of the differential image. To achieve this, the camera (2) records images of the door (4). The images of the door (4) are evaluated and the open state of the door (4) is established on the basis of the differential image between the closed state and the opened state.
